The stack of chips isn't high enough. Let's put a GAL in there for address decoding and control signal transformation. Jumpers to change the address map or additional inputs to the GAL. Will the dumb ideas ever end? Probably not.

Stacking address latch for the RCA CDP1800 family. The 1800 series CPUs have a muxed address bus on dedicated address pins. This is different than Intel, Motorola and others that have a muxed data/address bus.

As I was going through this magazine, this article shows the small form factor of the ZX81 comes in handy in using it as a stand along computer. I would would worry about its reliabiity. #zxspectrum #zx81 #retrocomputing

Triple video DAC for use with FPGA dev board. Can be used for composite, component and VGA.

obsessive thoughts continue early digital computers used tubes & germanium diodes then DTL SOT-23 dual diode can be placed under DIP switch crazy like a possum

brainworms This was a simple circuit in my head. Minimal component count. Easy to build. Weekend project. My staff tell me "Just a few lines of VHDL. You won't burn yourself with the soddering iron"

Stupid 555 trix Led flasher done wrongly eXperiment with components values and supply voltage No video because PotatoCam can not accurately show the beauty of this circuit. YOU MUST BUILD THIS

. What would you do if you had a million dollars? I’ll tell you what I’d do, man: two circuits at the same time, man That’s it? If you had a million dollars, you’d do two circuits at the same time? Damn straight. I always wanted to do that, man. And if I had a million dollars I could hook that up

. Are you one of the lucky few that have an ULTRA RARE LM3914? Do you believe that microcontrollers are just a passing fad? Here is a circuit that will keep you entertained for countless milliseconds. #analogpurity

BoB for another weird package that was used mostly in the 80s/90s.

I've been through the desert on a possum with no name It felt good to be out of the rain In the desert, you can remember your name 'Cause there ain't no one for to give you no pain

Thinking about possible replacements for the LM3914/15/16 that are no longer made by TI/NS. Many possibilities. An 8 pin MCU can drive a 12 LED charlieplexed array. [That's two louder than ten.]

The native Elbonians made use of the entire opossum. Nothing went to waste.

This came to me in a dream.

A 2D illustration of Ribbit's face, a green anthropomorphic frog character from The Amazing Digital Circus. There's three rows of her face. First row shows her face once and is labeled Ribbit. The second row shows her four times and says Rib-nibble. The third row shows her face eight times and says Rib-byte.

Dina font in 7x15 and 8x16 sizes. Normal, bold, normal italic and bold italic. Converted from BDF to C arrays suitable for use with small monochrome LCD and OLED that use 8 pixel high stripes (pages). C code: www.compendiumarcana.com/misc/font_di... Original: www.dcmembers.com/jibsen/downl...

I needed a font with 16, 24, and 32 pixel heights for a project. Did some searching and found a font called Spleen that had those sizes and more. Converted it from BDF to C arrays suitable for use with common small monochrome LCD and OLED that used 8 pixel high stripes (pages).

No human being would stack chips like this. address latch + RAM + ROM
